Some Important Terms and Abbreviations/ ICT Glossary


1. ABEND (Abnormal End)

When an application program ends earlier then expected due to some unforeseen error-often something which the programmer had not considered.

2. ADC (Analog to Digital Converter)

A device which converts analog information to digital.

3. ADSL (Asymmetric Digital Subscriber Line)

A mechanism by which data can be transmitted across conventional telephone lines. The circuit need to be configured to connect 2 specified locations.

4. AGP (Accelerated Graphics Port)

The Accelerated Graphics Port (AGP) is a high-speed point-to-point channel for attaching a video card to a computer system, primarily to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards.

5. ARP (Address Resolution Protocol)

ARP is a method for finding a host’s hardware address from it’s Internet address. The sender uses  the ARP to put forth a message seeking to delineate the IP address from the hardware address and waits to receive the latter. Each host maintains a cache of address translations to reduce delay and loading. ARP allows the Internet address to be independent of the hardware address but it only works if all hosts support it.

6. (ASCII) American Standard    Code  for  Information    Interchange

A   standard    coding    system   for   computers. ASCII-7  is a 7-bit code,  and  its extended  version,  ASCII-8 is an 8-bit code.

7. Array

A  data  type  that  is  a  collection   of  elements   in which  all  elements   are  of  the  same  type.  It  has  a  fixed number  of elements,  called  its length  or size, given  at the time  of its declaration.   All elements  of an array are stored in contiguous  memory  locations.

8. Asynchronous communication

Data transmission   mode in  which  sender   sends  data  at  any  convenient   time  and receiver  accepts it. In asynchronous   transmission,   data  is transmitted   character   by character  at  irregular  intervals.  That  is, a sender sends a character  at any convenient  time  and receiver  accepts  it. For instance,  transmission   of data from a terminal to  a computer   is asynchronous    because  during  data  entry  by an  operator,   time  between   successive   keystrokes varies.

9. ATM (Asynchronous Transfer Mode)

A networking standard which is predicted by many experts to be the networking protocol of the future.

10. Automated tape library

A mass storage device that uses a set of magnetic tapes, tape drives and a controller mounted in a single unit to function as a single large storage unit. Its typical use is for data archiving and as on-line data backup device for automated backup.

11. Auxiliary memory

A storage that supplements main memory of a computer. Often referred to as secondary storage this section of a computer’s memory is non-volatile and has low cost per bit stored, but its operating speed is generally far slower than that of primary storage.
